Preface
student. One of the distinctive features of this book is that it has been written
for the student. As one of the reviewers has said, "This book addresses the
student and not the professional." Thus, first and foremost, I feel the writing
style used to convey the concepts presented is the most important aspect of the
text.
Modularity. C, by its nature, is a modular langUage. Thus, the connection
between C functions and modules is made early in the text, in Section 1.2,and
continues throughout the book. To stress the modular nature of C, the first
complete main () function illustrates calling four other functions. The first
program that can be compiled is then presented, which calls the printf ()
function.
The idea ofargument passing into modules isalso made early,in Section 1.3,
with the use of the printf () function. Inthis manner, students are introduced
to functions and argument passing asa natural technique ofprogramming.
Software Engineering. Rather than simply introduce students to C, this text
introduces students to the fundamentals ofsoftware engineering. This introduc-
tion begins with Section 1.1,which introduces algorithms and the various ways
that an algorithm can be described. An example illustrating three algorithms
for summing the numbers from. 1 to 100 (Figure 1-4) is used to make the
discussion of algorithms more tangible to students.
The increased emphasis on software engineering is supported by a section
(Section1.5)on top-down program development. Here the importance ofunder-
standing the problem and selecting an appropriate algorithm is highlighted and
the relationship between analysis, design, coding, and testing introduced. Prob-
lem solving within this context is stressed throughout the text.
Applications. Engineering and scientific examples are used throughout the
text to illustrate the concepts presented. In addition, the majority ofthe chapters
have a section consisting of two specific applications relating to the material
presented in the chapter. Many of the applications are of the "tried and true"
variety and are not unique to this book. However, some interesting new
applications have been added, such as the study of acid rain, the calculation of
pollen counts, the operation oftelephone switching networks, and the construc-
tion of a user-written random number generator that are not typically found in
introductory texts. Additionally, Chapter 9 is completely devoted to numerical
applications and is a mini-introduction to numerical techniques in and of itself.
Emphasis on ANSI C.Although ANSI C is emphasized throughout the text,
pre-ANSI C constructs are also shown for those of you who will be using a
non-ANSI compiler. Generally, the major difference of note is in Chapter 6,
where user-written functions are introduced. For these functions ANSI C
requires asingle function header line that includes argument declarations, while
pre-ANSI compilers require argument declarations on a separate line. Also, the
declaration of functions in ANSIC,called function prototypes, includes the data
types of all arguments, while pre-ANSI C omits the argument declarations.
Introduction toPointers. One of the unique features of this text is its method
of introducing pointers. This is done by first using the printf () function to
ix
Preface
display a variable's address so that the student can "see" what an address is.
This approach, which was used in a A First Book of C, always seemed a more
logical and intuitive method of understanding pointers than the alternative
indirection description with no display.
Sincethe publication ofA First Book of C,the use ofthe print f () function
to display addresses has become a standard way of introducing pointers.
Although this approach, therefore, is no longer a unique feature of the book, I
am very proud of its presentation, and continue to use it in this text.
Program Testing. Every single C program in this text has been successfully
compiled and run under Borland's Turbo CCompiler. The programs have been
written using features fully supported under ANSI C. A source diskette of all
programs is available to adopters.
Pedagogical Features
To facilitate my goal of making C accessible as a first level course, I have
continued to use the following pedagogical features:
End of Section Exercises. Almost every section in the book contains numerous
and diverse skill builder and programming exercises.Additionally, solutions to
selected exercises are provided in an appendix.
Pseudocode and Flowchart Descriptions. As in A First Book of C,pseudocode is
stressed throughout the text. Although flowcharts were used in A First Book of
C,no explicit definition or introduction to flowchart symbols was presented. In
this edition we have added additional material on flowchart symbols and the
use of flowcharts in visually presenting flow-of-control constructs.
Common Programming Errors and Chapter Review. Each chapter ends with a
section on common programming errors and a review of the main topics
covered.
Appendices and Supplements
An expanded set of appendices has been provided in C for Engineers and
Scientists. In addition to the three appendices taken from A First Book of C on
Operator Precedence,ASCIIcodes,and I/O-Standard ErrorRedirection, the new
appendices contain material on Program LifeCycle;using the DOS,UNIX,VAX,
and PRIME operating systems; using Borland's Turbo C Compiler; and using
Microsoft's C Compiler.
Additionally, a printed solutions manual is available containing solutions
(with comments) to programming exercisesnot included in Appendix H of the
text. A so~rce diskette of solutions to all programs in the book is available to
adoptors of the text.

Acknowledgments
Acknowledgments
Cfor Engineers and Scientists is a direct result of the success (and the limitations)
of its predecessor, A First Bookof C. In this regard, my most heartfelt acknowl-
edgment and appreciation goes to the instructors and students who found the
earlier edition to be of service to them in their respective quests to teach and
learn C.
Once an edition devoted to engineering and scientific applications was
planned, its completion depended on many people other than myself. For this
I especially want to thank the staff of West Publishing Company for their many
contributions. These included the continuous faith and encouragement of my
editor, Richard Mixter, and developmental editor, Keith Dodson, and the many
suggestions and enthusiastic work of the production editor, Thomas ModI, and
promotion manager, Ellen Stanton.
The direct encouragement and support of my dean at Fairleigh Dickinson
University, Dr. Paul Lerman, must also be acknowledged. Without his support
and the support of my chairman, Dr. G. Naadimuthu, this text could not have
been written. I also wish to express my gratitude to the individual reviewers
listed on the next page. Each of these people provided suggestions and critical
comments that have made an invaluable contribution to the quality of this text.
Finally, I wish to acknowledge the patience, understanding, and love pro-
vided by my wife and partner, Rochelle.
